Abstract EN
The purpose of recommendation systems is to help users find effective information quickly and conveniently and also to present the items that users are interested in.
While the literature of recommendation algorithms is vast, most collaborative filtering recommendation approaches attain low recommendation accuracies and are also unable to track temporal changes of preferences.
Additionally, previous differential clustering evolution processes relied on a single-layer network and used a single scalar quantity to characterise the status values of users and items.
To address these limitations, this paper proposes an effective collaborative filtering recommendation algorithm based on a double-layer network.
This algorithm is capable of fully exploring dynamical changes of user preference over time and integrates the user and item layers via an attention mechanism to build a double-layer network model.
Experiments on Movielens, CiaoDVD, and Filmtrust datasets verify the effectiveness of our proposed algorithm.
Experimental results show that our proposed algorithm can attain a better performance than other state-of-the-art algorithms.
